iOS engineer. Shipped iPhone software. Fitness technology.
San Francisco · Portfolio · GitHub · Codeberg · LinkedIn
I’m an iOS / Full Stack Engineer at ShowFlex, a shipped iPhone fitness product available on the App Store. My work connects Swift, SwiftUI, MapKit, Firebase, structured data and technical delivery. I’m interested in iOS developer, Forward Deployed Engineer and fitness-technology opportunities. Forward Deployed Engineer is a target role, rather than a held title.
Additional confirmed profiles: Linktree · X · Medium · Hashnode author profile · DEV technical writing.
iOS/Full Stack Engineer · 2024–present
Prototype work: AI-assisted physique and posing feedback; Predictive competition features.
Product Development Manager · 2023–2025
Co-owner · 2017–2023
Dates are recorded at year precision. Supported work facts were approved on October 2, 2026; the NASM PBC credential was approved October 3. Academic details remain unresolved. Robin confirmed additional NASM credentials on October 3; individual verification links will follow.
APPLIED AI PROTOTYPE
Robin Winters built TORos for Yukon Systems: a prototype, model-agnostic, multimodal decision engine that uses deliberation among multiple models to reach consensus.
Prototype status; no production deployment or measured accuracy/reliability claim. Development dates and collaborator credits are not yet documented. The company article provides dated prototype evidence; my contribution is first-person confirmed. Consensus does not guarantee correctness.
PRODUCT EVIDENCE
Native iOS and fitness event discovery. The public iPhone listing describes map and calendar features. My contributions are outlined in the work history; the listing establishes product availability, rather than independently verifying individual authorship.
EDUCATIONAL SWIFT EXAMPLE
A standalone concurrency example covering obsolete results, errors and cleanup, cancellation and stable selection. Seven Swift Testing checks passed on macOS with Swift 6.4.
EDUCATIONAL SWIFT EXAMPLE
A Swift library and command-line tool with explicit timestamps, source-scoped identity, duplicate handling and conflict receipts. Synthetic fixtures; 12 passing macOS tests and checked command-line failure behavior.

The two Swift examples were prepared with coding-assistant support. They are separate from private ShowFlex source, released product integrations and customer deployments. macOS checks do not establish iPhone-device or Linux execution.

Browse nine articles, including my existing writing on on-device moderation and distributed sensing. Architecture proposals and author-reported experiments remain distinct from verified releases.
These versions preserve the same approved held roles and dates. The current PDF, JSON and plain-text versions include the TORos and the three confirmed NASM credentials; the original PDF preserves the earlier approved Word resume. The application variants emphasize different responsibilities without changing work history.
